Are you not then turning that person dead or alive, into a god or idol, and therefore serving Satan? Christ taught us how to pray by giving us the Lord’s Prayer beginning “Our Father”. Jesus told His disciples not to even ask Him for anything after He was gone, but to ask the Father for things in His name. Therefore do not pray to anyone other than God.
Is this following God or Satan, and again you have to conclude that it is Satan that they are following, as we are told that you are not to add or take away from the word of God. And if you are taking his word out of context then you are truly adding to His word.
